Background: Prostate cancer therapy with surgical or chemical castration with GnRH agonists has been linked to elevated FSH levels, which may contribute to secondary health disorders, including atherosclerosis and diabetes. Although recent findings suggest a role for FSH beyond the reproductive system, its metabolic impact remains unclear and difficult to disentangle from that of androgens. In this study, we examined the metabolic changes induced by FSH and distinguished them from those caused by testosterone.

Background: The utilization of PD1 and CTLA4 inhibitors has revolutionized the treatment of malignant melanoma (MM). However, resistance to targeted and immune-checkpoint-based therapies still poses a significant problem.

Objective: Here, we mine large-scale MM proteogenomic data to identify druggable targets and forecast treatment efficacy and resistance.

Article Synopsis
  • Selective antegrade cerebral perfusion (SACP) is a technique used to maintain brain blood flow during aortic arch surgeries that require temporary stopping of blood circulation, with two methods: bilateral (bSACP) and unilateral (uSACP), each having its risks.
  • A new predictive method was developed and tested to determine cerebral perfusion pressures (CPP) during SACP, helping surgeons decide which SACP approach to use preoperatively, utilizing patient-specific imaging and simulations.
  • The study involved five patients and demonstrated that the prediction method was accurate, with minimal errors in CPP predictions, highlighting the importance of collateral artery size for accurate modeling in surgical planning.

Higher-Level Gait Disorder (HLGD) is a type of gait disorder estimated to affect up to 6% of the older population. By definition, its symptoms originate from the higher-level nervous system, yet its association with brain morphology remains unclear. This study hypothesizes that there are patterns in brain morphology linked to HLGD.

Background: Infusion testing is an established method for assessing CSF resistance in patients with idiopathic normal pressure hydrocephalus (iNPH). To what extent the increased resistance is related to the glymphatic system is an open question. Here we introduce a computational model that includes the glymphatic system and enables us to determine the importance of (1) brain geometry, (2) intracranial pressure, and (3) physiological parameters on the outcome of and response to an infusion test.
